error handling

[scott212]

I have some code in a function that has a die statement with a message. I want it to give me back an error message on fail but I don't want it to stop loading the rest of the page. What should I do?

Just use [tt]or echo "Error: error message here";[/tt] instead then or make your own function to handle errors and then you could do something like this:
[code]<?php
$link = mysql_connect("localhost","root","") or echo "MySQL error: ".mysql_error()."<br />";
?>[/code]

You could also use trigger_error: [code]<?php
$link = mysql_connect("localhost","root","") or trigger_error(mysql_error(),E_USER_ERROR);
?>[/code]

IMO error handling should be done in the calling code. Have your function return true on success or false on failure, then let your calling code handle the error. eg;

[code]
<?php
 if (foo()) {
   echo "success";
 } else {
   echo "failed";
 }
?>
[/code]

Both of these are excellent suggestions. Thorpe- So would you treat your way similar to throwing exceptions by having a corresponding if-else for each possibility of true or false? I suppose otherwise you might not have any idea which method it came from making debugging a pain in the arse.
